300ml hydrothermal synthesis reactorThe cleaning, maintenance, and upkeep methods mainly include the following aspects:

1、 Cleaning methods

1. Daily cleaning:

After use, the kettle should be allowed to cool naturally to room temperature to avoid metal fatigue caused by sudden cooling.

When emptying the reaction solution, it is necessary to follow the chemical waste disposal regulations and neutralize corrosive substances before discharge.

Adopting a three-step cleaning method: first, rinse the inside of the reaction kettle with warm water to remove most of the residue; Then soak in a specialized cleaning agent for a period of time to perform deep cleaning on difficult to remove stains; Finally, rinse with ultrapure water for a second time to ensure that there are no residual cleaning agents.

2. Cleaning of key areas:

Pay special attention to the cleanliness of concealed areas such as the kettle lid threads and sealing grooves, as these areas are prone to accumulating residues that can affect the sealing performance.

Regularly clean the sealing ring, remove the sealing ring, check if there is dirt on the shaft, wipe it clean with a soft cloth, then apply a small amount of vacuum grease or silicone grease to keep the shaft and sealing ring smooth, and then reinstall them.

2、 Maintenance methods

1. Regular inspection:

Regularly inspect the kettle body, kettle cover, mixer, heater and other components to ensure that there are no defects such as cracks, deformation, corrosion, etc.

Check if all valves, joints, and seals are securely fastened to prevent leakage.

2. Replace the seal:

The sealing ring is a critical component, and it should be replaced immediately when it is found to be worn or aged.

When replacing, it is necessary to ensure that the new sealing ring fits tightly with the original components without leakage.

3. Lubrication and corrosion prevention:

Regular lubrication should be applied to bearings, seals, and other parts to reduce wear and tear.

For reactions containing corrosive substances, anti-corrosion treatment should be carried out on the kettle body and lid, such as applying anti-corrosion coatings or using corrosion-resistant materials for manufacturing.

3、 Maintenance methods

1. Temperature and pressure calibration:

Regularly calibrate the temperature and pressure system to ensure accurate and error free measurements.

2. Safe operation:

Strictly follow the operating procedures and do not arbitrarily change the experimental conditions and parameters.

Operators must wear protective equipment that meets safety requirements, such as gloves, goggles, protective clothing, etc.

The laboratory should be equipped with a good ventilation system and fire extinguishing equipment to cope with possible emergency situations.

3. Recording and archiving:

Detailed records should be kept for each maintenance and repair, including repair time, work content, replaced parts, etc., for easy reference and management in the future.

4. Shutdown handling:

When not in use for a long time, the reaction kettle should be cleaned and dried, and stored in a cool and dry place.

After shutdown, all PTFE switches should be loosened to avoid long-term locking that may cause the connector to bite or the PTFE piston to deform.

The cleaning, maintenance, and upkeep of the 300ml hydrothermal synthesis reactor require meticulous attention to ensure the normal operation of the equipment and the accuracy of experimental results. In daily use, it is necessary to strictly follow the operating procedures and conduct regular maintenance and inspections.
